Ultra-fine inorganic fibre spray coating heat preservation sound-absorbing external thermal insulation system
Technical field
The utility model relates to a kind of construction wall structure, is specifically related to a kind of external thermal insulation system of ultra-fine inorganic fibre sprayed coating.
Background technology
The body of wall that generally uses adopts structure as follows at present: body of wall, body of wall are outside equipped with the ultra-fine inorganic fibre sprayed coating, and the ultra-fine inorganic fibre sprayed coating directly is provided with decorative layer outward.Owing to decorative layer directly is set, and the inorfil sprayed coating itself has certain water imbibition, does not possess water-proof function, can't stop the infiltration of steam outside the inorfil sprayed coating.Phenomenons such as and after inorfil sprayed coating suction, its heat-insulating property can descend, and repeatedly after the suction, that spray coating heat preservation layer structure can occur is loose, come off.When serious and cause basic unit's body of wall to leak, the durability of spray coating heat preservation layer can variation simultaneously.Can't satisfy the weatherability of outdoor adverse circumstances, not reach the code requirement of country external wall outer insulation.
Summary of the invention
At existing defective in the background technology, the utility model provides a kind of durability better ultra-fine inorganic fibre spray coating heat preservation sound-absorbing external thermal insulation system.
The technical solution adopted in the utility model is as follows: a kind of ultra-fine inorganic fibre spray coating heat preservation sound-absorbing external thermal insulation system, comprise foundation wall, and foundation wall is disposed with ultra-fine inorganic fibre spray coating heat preservation layer, water-proof crack-resistant layer and decorative layer outward.
The ultra-fine inorganic fibre spray coating heat preservation layer of ultra-fine inorganic fibre spray coating heat preservation sound-absorbing external thermal insulation system of the present utility model is the sprayed coating of glass wool or rock wool and water base extraordinary environmental protection cementing agent.
The water-proof crack-resistant layer of ultra-fine inorganic fibre spray coating heat preservation sound-absorbing external thermal insulation system of the present utility model is the three layer construction that water-proofing anticracking screed, alkali resistant glass fibre open weave cloth and water-proofing anticracking screed are formed.
The utlity model has following beneficial effect: owing to also be provided with the water-proofing anticracking screed between the ultra-fine inorganic fibre sprayed coating of ultra-fine inorganic fibre spray coating heat preservation sound-absorbing external thermal insulation system of the present utility model and the decorative layer, so make whole outer heat preservation system durable, weatherability is better.
Description of drawings
Fig. 1 is the structural representation of the utility model ultra-fine inorganic fibre spray coating heat preservation sound-absorbing external thermal insulation system.
The specific embodiment
As shown in Figure 1, a kind of ultra-fine inorganic fibre spray coating heat preservation sound-absorbing external thermal insulation system comprises body of wall 1, body of wall 1 outer ultra-fine inorganic fibre sprayed coating 2, water-proofing anticracking screed 3, alkali resistant glass fibre open weave cloth 4, water-proofing anticracking screed 5 and the decorative layer 6 of being disposed with.Wherein water-proofing anticracking screed 3, alkali resistant glass fibre open weave cloth 4 and the water-proofing anticracking screed 5 three laminated water-proof crack-resistant layers that are.The inorfil sprayed coating can use any in several inorfil cottons such as the glass wool of hydrophobicity (not hydrophobicity) or rock wool in the specific implementation process.
The construction technology of inorfil spray coating heat preservation sound-absorbing external thermal insulation system is as follows: body of wall base treatment-scratch coat sprays the spraying equipment of the cotton and water base extraordinary bonding agent of glue-with inorfil by complete advanced person's specialty in advance and is applied to the building substrate surface, form airtight, jointless spray coating heat preservation layer (inorfil spray coating heat preservation layer thickness is decided according to design, and supposition design here need be thick for 30mm)-surface rolling shaping, repairing-smear the water-proofing anticracking mortar to smear the alkaline-resisting grid cloth of pressure-cladding finish coat construction immediately.
Inorfil spray coating heat preservation laminar surface in the above-mentioned construction technological process is also smeared and is provided with the thick water-proof crack-resistant layer of 4mm, does not have the cavity bonding so formed inorfil spray coating heat preservation layer and basic unit's body of wall.The water-proofing anticracking overcoat adopts the compound alkali resistant glass fibre open weave cloth of anticracking grout, and surface layer adopts dry-hang stone, cladding curtain wall, cladding aluminum-pinch etc.
Inorfil spray coating heat preservation sound-absorbing external thermal insulation system is applicable to the outer heat insulating work of different climatic provinces curtain wall formula external wall.Foundation wall can be concrete, building-block, materials such as lightweight filling masonry, loam brick and non-clay brick.
